[Samba] Moving to Bind from internal Ubuntu Server

[Szymon Życiński]

Hello

I'm trying to move to Bind from internal DNS. Internal DNS sometimes 
does not answer for clients with forwarded from another one records. It 
serves only local addreses when there is high traffic.

When i start bind is see some errors:
-----------------------------------
Apr 25 13:50:35 PrimaryDC named[7726]: sizing zone task pool based on 5 
zones
Apr 25 13:50:35 PrimaryDC named[7726]: Loading 'AD DNS Zone' using 
driver dlopen

----------------------------------------

In /etc/apparmor.d/usr.sbin.named i added lines:
   /usr/local/samba/private/** rkw,
   /usr/local/samba/lib/bind9/** rkw,
   /usr/local/samba/private/dns/** rkw,
